python2.7pip报错：UnicodeDecodeError: ‘ascii‘ codec can‘t decode
找到文件：<yourpath>\Python27\Lib\ntpath.py，修改join函数：
# Join two (or more) paths.
def join(path, *paths):"""Join two or more pathname components, inserting "\\" as needed."""import sysreload(sys)sys.setdefaultencoding('gbk')result_drive, result_path = splitdrive(path)for p in paths:p_drive, p_path = splitdrive(p)if p_path and p_path[0] in '\\/':# Second path is absoluteif p_drive or not result_drive:result_drive = p_driveresult_path = p_pathcontinueelif p_drive and p_drive != result_drive:if p_drive.lower() != result_drive.lower():# Different drives => ignore the first path entirelyresult_drive = p_driveresult_path = p_pathcontinue# Same drive in different caseresult_drive = p_drive# Second path is relative to the firstif result_path and result_path[-1] not in '\\/':result_path = result_path + '\\'result_path = result_path + p_path## add separator between UNC and non-absolute pathif (result_path and result_path[0] not in '\\/' andresult_drive and result_drive[-1:] != ':'):return result_drive + sep + result_pathreturn result_drive + result_path
加入下面的代码在函数体中：
import sys
reload(sys)
sys.setdefaultencoding('gbk')
